Abstract:
A pushbutton switch member has a dome-shaped movable contact and an operation key facing and separated from a movable contact. Pushing the operation key toward the movable contact causes the movable contact to electrically connect at least two contacts on a substrate. The operation key is provided with: a key; a dome connected with an outer periphery of the key, and deformable by pushing of the key toward the substrate; and a foot connected with an outer periphery of the dome, and fixed on the substrate. The movable contact is provided with: an upper contact spaced apart from a site directly below the key, and which makes contact with a contact when the key is pushed in; and an outer fixing part disposed at the upper contact, or further outside thereof in the radial direction, and fixed outside of the key in the radial direction.
